--- Comment #14 from Robin Dapp <rdapp at gcc dot gnu.org> --- Ok, running tests with the adjusted version and going to post a patch afterwards. However, during a recent run compiling insn-recog took 2G and insn-emit-7 as well as insn-emit-10 required > 1.5G each. Looks like they could cause problems as well then? The insn-emit files can be split into 20 instead of 10 which might help but insn-recog I haven't had a look at yet.
